Use our AR15Part.com Anti-Walk Pins for a refined fire control system. Removing all the slop between the trigger, hammer, pins and the receiver results in that extra bit of enhancement to get the maximum performance potential out of high-grade trigger parts.

Pis diameter is .156" for standard small pin receivers, these tool steel trigger/hammer pins are black oxided for corrosion resistance and retained by buttonhead retainer screws with thread locker on both ends.

No modification to the lower receiver is needed, but be aware that the trigger and hammer may have to be reamed for a perfect fit with these parts, and a detail stripping of the lower receiver will be required in most cases

Comes with 4 screws, 2 pins, 2 allen wrenches and pin guide tip for easy installation.
